Pond Dye for Water Gardens

This concentrated blue dye treats up to one acre-foot of water in decorative ponds and fountains. The powder formulation comes in four 16 oz bags for repeated applications. It is non-toxic and designed for water garden use.

Effective pH range limits treatment

The dye works within a pH range of 5.5 to 8.5 for standard treatment, with an extended tolerance up to 9.5. Water outside these limits may reduce colour intensity or longevity. Regular testing ensures the product performs as expected.

Check pond volume and water chemistry

Measure your water feature to confirm it falls within the one acre-foot coverage per package. Verify the current pH sits between 5.5 and 8.5 before dosing. Ensure you have storage space for the remaining bags, which have a two-year shelf life.
